A transverse harmonic wave on a string is described by \(y(x,t) = 3.0 sin ( 36t + 0.018x + {\pi \over 4})\) where x and y are in cm and t in sec. The positive direction of x is from left to right.
What is the shortest distance between two successive crests in the wave?
1. 1.3 m
2. 3.0 m
3. 2.5 m
4. 3.5 m
